If your Toshiba laptop shows no signs of life, a dead CMOS battery could be the culprit. The CMOS battery powers the laptop's BIOS settings and clock. Try the following steps:
1. Check the power cord: Ensure it's securely plugged into both the laptop and the wall outlet.
2. Power button: Press the power button for 30 seconds to discharge any residual power.
3. CMOS battery: Locate the CMOS battery (usually a small round battery, like a watch battery, located on the motherboard). Remove it for 30 minutes to an hour to reset the BIOS.
4. Reinstall the CMOS battery: Put the battery back in its original position.
5. Try to power on: Press the power button to see if the laptop turns on.
If the laptop still doesn't show any signs of life, it's possible that the issue is more serious and requires professional attention. You may want to contact Toshiba support or a authorized repair center for further assistance.
Keep in mind that if the laptop has been inactive for an extended period, the main battery may also be drained. Try charging it for a few hours before attempting to turn it on.
